These subs are exactly what I was looking for. I hade 2 10s in a huge ported box but I wanted to downsize and save some space in my hatchback and still have some good bass. I bought 3 of these and I tried a ported box and built it bigger than the specs required. I was less than impressed with that so I tried a sealed box built to specs exactly and it was better but I still felt like they could do more so I tried the ported box again but this time gave each sub their own chamber at about 0.47 cuft per sub with a 1 1/2 inch diameter x 8 inch long port in each and holy cow they came alive. My wife said I was shaking the whole house when I was in the driveway. These easily pound as hard as the 2 10s I had and even handle the low bass with ease. The 35hz-50hz range was very impressive for the size. They seem a little power hungry so I'm wondering if the power handling per specs is under rated. So if you want good bass and are limited on space these things will/can get the job done, just power them good, build the box exactly per specs and give them some break in time. Also, the price onlinecarstereo.com had these were about $30-$40 cheaper per sub than other online dealers.
